Abstract
If and when extrasolar planets pass in front of their
stars, we are presented with a golden opportunity to
learn about the nature of these objects. Transiting
systems allow us to estimate the planet's radius and mass,
and, by inference, its composition. Furthermore, the planetary
atmosphere can be studied directly, both in absorption,
and in reflected light. Indeed, the lure of transits has
convinced more than 20 groups worldwide to follow its dark
path... and who knows whether planets await us at the end?
